Want cork in your home? Yes? Then check out Jelinek Cork's group of websites, which each will tell you more about cork and its uses than you ever knew (and thanks to Holly for pointing it out).
Jelinek Cork is an old European company that has adapted over the years to serve industry needs and now also is "dedicated to protecting the eternal continuity of the cork oak tree" while celebrating its many uses, of which sound absorption, good acoustics and thermal insulation are some.
Of chief interest to us is their CorkStore.com, which offers cork products online at factory outlet prices. You can shop here for cork rolls & sheets, flooring, pads, furniture and other cork products.
Jelinek Cork have three lines of cork floor tiles which are easy to install, the cheapest of which is called Cork Decor. These 12" square tiles run from $2 to $4.20 a tile, and come in MANY shades and patterns. These can be glued to a subfloor, while their Floating Floor line is a tongue and groove snapping affair that requires not glue at all.
